There's an article in this morning's Chicago Tribune hinting or suggesting that Shreck should or could strike some sort of deal with Goodman Theatre in order to make the Broadway production part of an upcoming season. Something similar was done in past years with I Am My Own Wife and van Hove's A View from the Bridge.
I was under the impression that she would be performing in it at the Mark Taper Forum in Los Angeles, but I see now on the website that she is credited as author but that casting is still to be announced.
